neuro-cardiac rehabilitation in youth with congenital heart disease (qualineurorehab)

Conditions: Congenital Heart Disease

Summary: remarkable progress in paediatric cardiology and surgery have led to the substantial increase of congenital heart disease (chd) survivors. long-term outcomes in rare and complex chd have become a critical priority as three major sources of morbidity have been identified in this population: neurodevelopmental sequelae, mental health issues and reduced exercise capacity. these challenges adversely affect their quality of life and constitute a major public health issue. we seek to evaluate the efficacy of the first integrative and holistic program in neuro-cardiac health associating physical and psychological rehabilitation for children with rare chd compared to the standard of care. children randomly assigned to the intervention will undergo a 12-week neuro-cardiac intervention including home-based adaptive physical exercise, telehealth parent and child psycho-education and child computerized cognitive training, as well in-person individual sessions of intervention reinforcement. parents will be actively involved and will receive personalized feedback and educational resources. children assigned to the control group will receive the standard of care in congenital cardiology. post-intervention effects will be measured after 12-months on several outcomes including health-related quality of life (hrqol), trained and untrained cognitive skills, mental health outcomes and cardiovascular/physical variables.

neurodevelopmental and mental health issues and reduced exercise capacity are the most frequent long-term morbidities in youth with chd. these problems worsen with age and play a critical role in reducing the quality of life of patients and their families. the quali-neurorehab chd multicentre, randomized controlled trial seeks to test the efficacy of an innovative home-based neuro-cardiac intervention to improve physical and mental health of children, adolescents and young adults with rare chd, as assessed by the patients themselves using patient-reported outcomes and standardized assessments. outcomes relate to changes in scores for health-related quality of life (hrqol, primary outcome measure), neurodevelopmental and mental health outcomes, and cardiopulmonary exercise test parameters, 12 months post-enrolment, in patients with rare chd aged 8 to 25 years old. this is a two-arm parallel design study: intervention versus control. intervention using the neuro-cardiac rehabilitation program will be the active arm. standard of care will be used for the control group and involves normal cardiology consultations and follow-up without intervention programs on physical activity or neurocognitive training. the intervention group will include 12 weeks of neuro-cardiac training, comprised of at-home adaptive physical exercise, telehealth consultations and computerized neurocognitive training as well in-person individual sessions of intervention reinforcement. we hypothesize an increase in the overall hrqol score of 6 ± 14 points (over 100). with a 90% power, a bilateral alpha risk of 5%, and potentially 20% of loss to follow-up and/or missing data on the primary outcome, we expect to include 138 patients in each group (n= 276, overall). analysis will be performed using intent to treat (itt) approach. we predict significant positive changes in quality of life, mental and physical health scores in patients who will be assigned to the neuro-cardiac intervention (active arm). if this intervention is effective, it can have critical public health implications for the organization and modalities of care for children with rare chd in europe. a neuro-cardiac rehabilitation programme tailored to the specific challenges of individuals with rare chd would improve patient care pathways across major centers in europe.
